Fig. 8: A tethered goat patrols the roadside of her owner’s property. Note the infestation of blackberry on the neighbour’s roadside. Fig. 9: A close-up of the roadside at the junction of the two properties. Goats prefer blackberry leaves to pasture. Fig. 10: Photo taken in September shows Mr. C. G. Hawken, of Kopuku, standing among Glyceria aquatica which has replaced tall blackberry. Behind Mr. Hawken is to be seen the tali blackberry against which, this vigorous grass is advancing. Fig. 11: A slightly drier portion of the swamp on Mr. Hawken’s farm where the ground is dry under foot in winter and where phalaris arundinacea, with some assistance from the slasher and fire, has eliminated vigorous blackberry growth in twelve months. The white object is a handkerchief.
